Abstract

La présente invention concerne la conception de plaques bipolaires (30) destinées à être utilisées dans des cellules électrochimiques refroidies par conduction. La chaleur générée pendant le fonctionnement de la cellule est évacuée de la région active (60) de la cellule en direction de la périphérie de la cellule par l'intermédiaire de ladite/desdites plaque(s) bipolaire(s) de la cellule. Ladite/lesdites plaque(s) bipolaire(s) est/sont conçue(s) de manière à fonctionner comme des dissipateurs thermiques afin de recueillir la chaleur de la région active de la cellule et d'acheminer la chaleur vers la périphérie de la plaque où la chaleur est évacuée par des moyens traditionnels de transfert thermique. La délimitation de la/des plaque(s) bipolaire(s) peut être dotée de structures de dissipation thermique (43) pour faciliter l'évacuation de chaleur à partir des plaques. Afin que la/les plaque(s) bipolaire(s) puisse(nt) fonctionner en tant que dissipateurs thermiques efficaces, l'épaisseur de la/des plaque(s) bipolaire(s) peut être déterminée en fonction du taux de génération de chaleur dans la cellule pendant le fonctionnement, de la conductibilité thermique (k) du matériau sélectionné pour former la plaque et du gradient de température voulu dans une direction perpendiculaire à la plaque (ΔΤ).
